The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro
英文词汇:molecules,nucleus,protons,neutrons,electrons一定要加S么,为什么.还是一般情况?atom呢? 答案 就是单数复数啦...比如说proton就是一个质子,protons就是多个质子……氢就是one proton……在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】相关推荐 1英文词汇:molecule...
An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (t...

Atomic number (Z) = 92, Mass number (A) = 238 But we know that No. of protons = No. of electrons = Atomic number (Z) ∴ No. of protons = 92 and No. of electrons = 92 Further, No. of neutrons = Mass number - Atomic number A−Z=238−92=146 Show More ...
Atoms were once thought to be the smallest building blocks of the universe, until it was discovered that even they were constructed of building blocks of their own. Those building blocks are protons, electrons and neutrons, and with the advancement of sc
"Protons, Neutrons and Electrons" My observation, a useful table here showing the particle, mass in kg, radius in meters, and charge in coulombs. The radius of the proton is 0.83 x 10^–15 m, the radius of the electron is 10^–18-10^–22 m. An interesting report but how does the...
Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All...
